Specification of Letters Patent.

Patented May 1, 1917.

Application filed April 14, 1916; Serial No. 91,107.

To all whom it may concern:

Be it known that I, FRED E. SPARKS, a citizen of the United States, residing at Bellaire, in the county of Belmont and State of Ohio,'have invented certain new and useful Improvements in Sash Retainers and Fasteners; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention is a sash holder and lock designed more particularly for use with windows wherein the sashes are slidably mounted in the frame.

It is a purpose of the invention to eliminate the employment of sash weights and cords" by the utilization of resilient frictional devices carried by the sash to be placed in engagement with the frame to retain the sash in a desired position relative to the frame. The frictional devices are preferably formed in pairs which are yieldable longitudinally, such frictional devices being preferably in the form of roller bearings to permit of the slight longitudinal yielding found desirable in a device of this character. Where the frictional device consists merely of a spring actuated block positioned within the sash to engage the frame transversely of the slidable movement of the sash, such device serves to deflect the sash from its normal sliding position into an inclined position, causing the frictional device to become wedged between the sash and the frame.

i This device overcomes the objections found in the resilient plunger type of sash fastener in providing spaced plungershaving antifrictional engaging surfaces, which devices also serve as anti-rattlers for the sash.

The invention also includes a locking element which may be mounted for reciprocat ing movement between a plurality of the spaced resilient sash holding devices,- the lock operating to prevent movement of the sash when the foot of the lock is brought into frictional engagement with the window frame. The lock is also provided with means whereby its bolt cannot be retracted except through manually controlled instrumentalities. 7

Other objects and advantages of the invention will be come apparent from the following detail description of the invention,

taken in connection with the accompanying drawings and the appended claims.

While the preferred embodiment of the invention is disclosed in the accompanying drawings, it is to be understood that the construction therein set forth is for the purposes of illustration only, and not as defining the limits of the invention. I

The casing indicated at 1 may be of any suitable material, such as metal, and may be formed in any preferred manner, as by casting. The casing is preferably provided with wings 2, 3, whereby the casing may be securedto a window sash indicated at 4. The sash may be cut away to insert or inlay the casing 1, or the device may be applied in any other manner found desirable. The casing 1 is preferably provided with a removable cover indicated at 5, and this cover may be provided with a rotatable element 6 having a key-hole 7 therethrough, and which element 6 may be provided with an enlarged portion 8 which is mounted to turn against the cover 5 in a suitable bearing formed in form of a pinion and in the drawings is shown as a mutilated pinion.

The casing 1 is preferably provided with guide-ways 9, 10, which may be integral with the casing 1, said guide-ways 9, 10 being the cover. This member 8 may be in the spaced apart to provide a channel for the locking mechanism, and. said guide-ways also forming an upper channel 11 and a lower channel 12 for the reception ofthe resilient frictional elements. The member 9 may be provided with a rib 13 extending across the channel 11, and may be provided also with a recessed end portion 14. Into the channel 11 is shown positioned a block 15 having a chamber formed therein to receive a resilient element, such as a helical spring 16 which may be retained in the chamber and extend beyond the same into the recess 14 of the casing 1. The block 15 is preferably provided with a cut-out portion 17 on one face thereof providing a shoulder 18 at one end of said cut-out portion and the limiting stop 19 at the other end of the cutout portion. The cut-out portion is adapted to receive the rib 13 of the member 9 to limit the reciprocating movement of the block 15 in the channel 11, by having the abutments 1S and 19 engage the rib 13. The end of the block 15 opposite to that carrying the spring 16 is preferably provided with a roller 20 rotatably mounted upon a pin 21. The lower channel 12 may be provided with a block 22 similar to the block 15 of the upper channel 11, and this block 22 may be cut away as at 23 to provide an elongated recess in which is positioned a rib 24 of the division section 10 of the casing, which limits the reciprocating movement of the block 22. ,Said block is preferably provided also with a roller bearing surface 25 mounted similar to that described in connection with the block 15.

The blocks 15 and 22 are preferably at opposite ends of the casing 1 and the frictional engaging surfaces 20, of the blocks cooperate to maintain the sash 4 in parallel relation to its frame, indicated at 26, when the sash is moved within the frame. Roller bearings 20, also permit of easy slidable movement of the sash 4 within its frame 26,

when force is applied to the sash. The sash fastener and lock may be inserted in the frame 26 instead of the sash 4, as shown in the drawings. and as may be preferred. The strength of the springs 16 of the device is sufiicient to prevent the sliding movement of the sash relative to its frame when no external force is applied to the sash, thereby eliminating the necessity for th employment of counterbalancing mechanism.

Combined with the spaced frictional engaging devices to maintain the window in a predetermined position, is a locking element, which is preferably mounted between the frictional engaging devices, and is designed to be manually moved to its locking position and provided with instrumentalities whereby the lock may not be released except by releasing a catch from engagement with the locking bolt.

The locking element is shown in the form of a bolt 27, the engaging surface or foot 28 of which may be knurled, roughened or otherwise provided with an engaging face which will bite into the material of the sash or frame and revent movement of the sash relative to the rame. The bolt 27 is cutaway as at 29 to provide a shoulder adjacent the engaging end of said bolt. The bolt is rovided at this cut away portion with a me 30 designed to cooperate with the pinion 8 carried by the plate 5, whereby when the pinion 8 is operated by a removable knob 31, the shank 32 of the knob cooperating with the key-hole 7 operates to rotate the pinion 8, which en ages the rack 30 and reclprocates the bolt 2 in the channel 33 of the casing 1. Rearward reciprocation of the bolt is limited by the end 34 abutting against the wall of the casing, while the forward movement of the bolt 27 is limited by the le 35'thereof engaging with a pintle 36 carrie b the bolt retaining device, as will be clear y understood from an inspection of Fig. 4.

The channel 33 is providedwith a recess 37, and is also provided with a substantially cylindrical plug 38 which is designed to serve as a rocker base for an arcuate end 39 of a lock retaining device 40. This lock retaining device is ada ted to be fitted in a cut-out portion of the Bolt 27 and to be positioned between the bolt 27 and the back wall of the casing 1. This lock retaining element is provided with resilient means, shown in the form of a leaf spring 41 adapted to be seated in the recess 37 of the channel 33, the end 42 of the spring being deflected to engage a shoulder 43 of the recess 37, which causes the lock or bolt retaining device to be pressed toward the bolt 27.

That portion of the bolt 27 which is cut away and faces the bolt retaining device 40 is preferably provided with teeth 44, and the bolt retaining device 40 may be provided with an extended flange which is adapted to ride over the teeth 44 and successively engage a tooth as the bolt 27 is advanced by the rotation of the pinion 8 to prevent the retractive movement of the bolt 27, the resilient element 42 acting against the casing 1 to always maintain the flange 45 into engagement with the teeth 44. The end 39 of the bolt retaining device is provided for rocking movement against the member 38, when said rocking movement is desired to move the bolt retaining device out of engagement with the bolt 27, as will be hereinafter explained.

The bolt retaining device is provided also with an extension 46 adapted to be seated in a cut-out ortion 47 of the rib 10 of the casing and tiiis extension may be provided with the axial element 36 on one side and with another element of similar character 48 upon the opposite side of the extension 46, the element 48 being seated within an aperture 49 of the casing 1, while the element 36 is designed to be seated in the recess 50 formed in the pinion 8.

The device may be applied to either the sash or the frame, so that the bearing members 20, 25 are placed in frictional engagement to hold the sash in predetermined positions. The element for actuating the lock, such as a knob 31, is preferably removable from the device and may be in the form of a key as shown in Fig. 11, in lieu of the knob 31, for convenience in carrying the retracting element. Whenthe lock has been advanced to its locking position, by the rotation of the pinion 8, by means of the knob 31 or the key, it is held in that position by the flange engaging the teeth 4d of the lock, and the sash cannot be moved in any position. When it is desired to retract the bolt, the key 32 must be inserted through the key-hole? until the shank 32 of the key bears against the end of the element 36, and

pressure must be applied to the key to depress the lock or bolt retaining device 40 Y by means of its element 36 to thereby release the flange 45 from engagement with the teeth 44L and while so pressing the key it should be rotated to cause the pinion 8 to engage the rack 30 to retract the bblt.

While various changes in the form and proportion of parts may be made, without departing from the spirit of the invention, the right is reserved to make such changes and alterations in the various details of construction herein set forth, as fairly fall within the scope of the appended claims.
